Supplements That Damage the Liver The supplements the study mentioned include: Ashwagandha , used to support the nervous and endocrine systems; improve sleep; and boost mood, energy and immune levels
Drug-induced liver injury (DILI) is a cause of acute and chronic liver disease caused specifically by medications and the most common reason for a drug to be withdrawn from the market after approval. The liver plays a central role in transforming and clearing chemicals and is susceptible to the toxicity from these agents.
Signs of a biotin deficiency may appear gradually, per the NIH. In the later stages, a biotin deficiency can cause: Hair thinning. Hair loss. A scaly, red rash around orifices. Dry, red eyes ...
Normally, the amount of biotin in the body is regulated by dietary intake, biotin transporters (monocarboxylate transporter 1 and sodium-dependent multivitamin transporter), peptidyl hydrolase biotinidase (BTD), and the protein ligase holocarboxylase synthetase. When any of these regulatory factors are inhibited, biotin deficiency could occur. [23]
Mutations in the BTD gene cause biotinidase deficiency. Biotinidase is the enzyme that is made by the BTD gene. Many mutations that cause the enzyme to be nonfunctional or to be produced at extremely low levels have been identified. Biotin is a vitamin that is chemically bound to proteins. (Most vitamins are only loosely associated with proteins.)
One important note: Excess biotin can also "cause incorrect results in certain laboratory tests that look at thyroid levels and blood markers that can help diagnose heart attacks," says Dr. Castillo.
Biotin, a B vitamin, is found in foods such as liver, egg yolks, and milk. It is essential for the normal production and breakdown of proteins, fats, and carbohydrates in the body. Mutations in the HLCS gene reduce the activity of holocarboxylase synthetase, preventing cells from using biotin effectively and disrupting many cellular functions.
